Appears to be a scammer caller
They were looking for my ex. I told them I'd give them a current number if they would tell me who they were, what this was regarding and how they got my number by accident. They wouldn't say.
When I answered the call it said it was from the irs and that my ss number was being suspended due to criminal activity. And to "press 1 now!"
